History & Geology
The Birimian Greenstone Belts of West Africa
July 2013 by Chris Ralph
The country we were to visit was Burkina Faso, a small country about the same size of my home state of Nevada with about 10 times more people. The second day I was in Africa, we went out to the goldfields for the first time.
Liberty and the Phoenix Mine
Liberty, Washington is located in the mountains near Yakima and Ellensburg. There is nothing much in Liberty except for about 20 houses on patented mining claims and a lot of dry holes.
Prospecting for Surface Flood Gold Placers on Low and Intermediate Gradient Streams
Sample panning is a very important method used to find the richest parts of a flood gold deposit before setting up equipment and running material.Enrichment of Mineral Deposits by Weathering—Part I
The exact minerals formed in the concentrated supergene deposits depends much on the type of country rock around the deposit and the chemistry of the deposit itself, but if conditions are right, this process will form some rich patches of bonanza ore, in some places valued at thousands of dollars to the ton.All About Garnets
I get a lot of questions from prospectors about garnets, their value and what they tell us about the geology of some types of mineral deposits. So I thought it would be a good idea to take a closer look at the lowly garnet and learn a bit more about it.
The Historic Gold Rush Town of Quincy
…we focused on various layers of hard-packed flood material out of the creek, and we also obtained some material up quite a ways from the creek itself on bedrock.
One Question, Forever Unanswered—Did He Really Find the Gold?
This was one of those stories where you have no doubt that the person telling it believes it to be true. But was it?
The Preacher of Sheeps**t Flats
It seemed that the preacher always gave the same answer to anyone who asked where his gold had come from. His answer was, “If you know your gold, you can find it. However, you will have to find it the hard way, the way I found it.”
